BUILDING MATERIAL.

SPECIFICATION forming part of Letters Patent No. 654,905, dated July 31,1900. Application. filed July 2, 1900. VSerial No. 22,309. (No modell)To @ZZ whom t may concern:

Be it known that I, MARK W. MARSDEN, a citizen of the United States,residing at Philadelphia, in the conntyof Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inBuilding Material, of Whichthe following is a specification.

The object of the invention is to provide a reproof material which shallbe compara-` tively inexpensive, strong,easil`y erected, and

well adapted for the reception of plaster.

vThe nature, characteristic features, and scope of my invention will bemore fully understood from the following description,takeu in connectionwith the accompanying drawings, forming part hereof, and in which-Figure lis a face View illustrating a partition without plaster andconstructed to embody features of my invention. Fig. 2 is a sectionalView taken on the line 2 2 of Fig. l. Fig. 3' is an edge View of one ofthe tie or distance pieces. Fig. et is a sectional view of a tie ordistance piece embodying a modification of the invention. Figs. 5 and 6are respectively face and sectional views illustrating a modification ofthe invention. n Fig. 7 is a plan view of sections of two overlappingbuilding-plates having the flanges in substantially the form oftruncated cones or frustums, the latter registering with each other attheir overlapping portions, as shown.

. Fig. 8 is a cross-section through a perforated plate the flanges ofwhich areslightly dished or concaved. Fig. 9 is a diagrammatic viewillustrating the mode of punching the plates. Fig. l0 is a modified formof plate with corrugations running parallel with the truncated cones orfrustums. i

Referring to the drawings, my improved partition is shown as consistingof sheets or plates l, preferably of sheet metal, and of distance or tiepieces 2. The sheets 1 are punched upso as to provide them with flangedopenings 3, which may be cylindrical, as shownin Figs. l and 2, orconical, as shown in Figs. 5 and 6. These openings are formed bypunching, stamping, or otherwise removing a circular blank in suchmanner that a continuous marginal flange or ring is formed, which ismade cylindrical or may have the form of a truncatedV cone or frustum,as in `as to leave a smooth' edge or surface.l By

cylindrical and conical I do not wish to confine myself to` the narrowdefinition of these terms, as While the general outline of the angesforms practically cones or frustunis they may be, and generally are,slightly dished or concaved, as shownin Fig. 8.

'l The mode of punching is illustrated in the diagram Fig.`9, and twillbe understood that the e plate is punched and raised inopposite'directions, so that if bnrs are formed they will naturally `beforced inward in respect to the flange. X indicates the plate, and X andX2 the male and female dies, respectively. The operation of thesedevices is well known to those skilled in the art and requires `nodescription here.`

The removal of the blank and the shaping of the ilangeare the result ofone operation, and it will be evident that the novel feature of havingthe annular lange formed as a continuous member besides'simplifying andreducing the cost of manufacture of the plates also compensates for themetal re'- moved and imparts increased structural strength to thepartition.

The perforations may be arranged in straight rows, as shown in Fig. 5,or they may be staggered, as shown in Fig. l. Each sheet l along one ofits edges, which, after erection is shown as the bottom edge, is slit orotherwise provided with tongues, as at 4, I

or may lap over-#for instance, as shown at the end in FigVl and indetail, Fig. 7. The tongues 4. may be bent at right angles to the sheetsand by' tacking them to the iloor serve in part to securethe partitionor wall. By bending the tongues of the superimposed sheets slightlybackward and forward they serve to engage thetop edge of the sheet uponwhich they are superimposed, andthus assist in holding the structure toplace. The distance or tie pieces 2 are cut or otherwise formed withserrated edges, so as to provide them with teeth 5. y The teeth 5penetrate certain of the perforations in each of two adjacent 'sheets orplates andare bent over, lso as to clench the same, andjthus not onlyassist in holding the parts of thepartition to place,

IOO

" but also in properlyholding the sides thereof which maybe provided inthe sheet or plate, i

1 andl that igure also shows the plates over- Y lapped at their'edgesand secured-bythe teethv to eV y v654,905

at a proper distance apart. n l Y In Fig. 2, v6 indicates plaster,andthe space 7 may be filled with any suitable incombustible material,if desired. y In Fig. 5, 8 represents additional openings,

5. 9 4represents a Vportion of a door-frame, to

which the sheets or plates may be attached Y by nails, screws, or like`fastening devices.

In Fig. 4 the distance or tie piece is shownf i corrugated, whereby itsstrength is increased.

Fig. 7 illustrates'the mode of overlapping* adjoiining edges of platesprovided with perforatiogns having flanges in the form of trun-4 catedvoonesor frustuins. v l

Fig, 8 is across-section through one of .the perforated plates,l showingthe flanges slightly I `ydished or concaved, as at l0, and having theburs 111 turned inward or reversely thereto.

` .Y Y- In ,-Fig. l0 I have shown a modified form of plate, in that the`same is provided with corrugations 12, running parallel to theperforations vand longitudinally andlaterally with respect to the plate.

Itis evident that instead of the distance or tie pieces2 I may employany suitable wellk-nown attaching means.

, It will be obvious to those skilled. in the art to which lfmyinventionappertains that modiications may be made inv detail without de-l partingfrom `the spirit thereof. yHence Ido not limit myself to thepreciseconstruetion and arrangement of parts hereinabove set forth andillustratedin the' accompanying drawings. For instance, it will beobvious that lI .do notI limit'myself to the use of the invention as .amere building-plate for partitions or Walls, as it is susceptiblev to,numer- 011s other uses `and applications. For example, it is ofpeculiar importance and value as a lining for steamships and othervessels. It Ican also be employed with `equal `facility and advantage asa support or foundation for a composition floor or pavement,which lattermayconsist of cement or may be made ornamental in any well-,known andappropriate` manner.
